This is the key element of batteries. Our company uses the self-developed new Pb-Ca-Sn alloy formulas as the framework of the polar plate to hold the active substance. It has excellent performance withstanding corrosion and in conductivity strength. The positive polar plate’s active substance is composed of lead dioxide and the negative polar plate’s active substance is composed of pure lead. The two stores or provide electric energy by means of chemical energy reactions between the power and the electrolytes inside the glass fiber separator, allowing the battery to be charged/discharged and used repeatedly. Besides optimal designs of the polar plate formulas, our company also enhanced our mixed-paste manufacturing technology for the battery’s active substance. With sophisticated control of particle size and crystal structure, we created the key technology of active substance 4BS, which has strong corrosion resistance, increasing the feasibility of the deep discharge of the battery under repeated usage and increasing life span.
